Specification of Letten Patent. l Patented Nov. 19,` 1918.

Appueation filed Jimeno, 191s. serial No. 240,941.

that may be readily closed or opened for aff fording complete protection to the passengers against weather and sea conditions, and for securing the necessary ventilation and the desired freeboard. Further objects include means for providing a water tight joint between the movable closure and the body of the vessel, means for operating the closure both from the inside or the outside of the boat, means for increasing the ships buoyancy in case of accidentalleakage, and means for folding the ships sail about the mast and housing the same when not requiredy for use. And the invention alsoincludes certain details of construction hereinafter set forth.

In describing the invention in detail, reference is had to the accompanying drawings, forming a part of "this specification, and wherein like characters of reference are used to designate corresponding parts through out the several views, and in which:

Figure 1 is a side elevation of the boat, showing the closure in closed position; Fig. 2, a ground plan of the same,with the closure open; F ig. 3, a transverse section through the boat and closure; Fig. 4:, an enlarged sec tional detail view of the marginal connections of the closure and the runway therefor; Fig. 5, a detail view of the mast connections, shown partially in section; A,and Fig. 6 is a detail sectional view' showing means for making a tight joint between the movable closure and the body of the boat.

In the drawings numeral 1 designates the hull or body of theboat, provided with the fore and aft closed deck sections 2 and 3 respectively, the same being spaced* apart and bounding amidship opening inthe deck arranged to be inclosed by thetwo-partiiexible folding closure 4:, the two parts or sections closing together at the top.

At their lower longitudinal ends, the closure sections are mounted upon` the rotatable hollow cylinders or drums 5, while their opposite upper ends are carried by longitudinal an le bars 6. The closure sections arey pre erably made of a double layer of flexible material 7, composed of canvas, or a union of canvas and rubber,the layers being connected together in any approved a manner and provided with a series of interposed longitudinal reinforcing wires or rods 8, to the terminals of which are secured the roller connections 9, arranged to engage the interior seats 10, formed on the runways 11. As herein shown, each runway is formed of two members, constituting a semicircular' frame, open at opposite ends, and provided along its inner face with ra slot, forming a passage for the roller connections 9. The runways are fixed to the opposite inner edges of the deck sections 2 and 3 by the rivets 12, and an exterior sliding joint is made between the same and the closure sections by means of the packing strips 13, the latter being preferably formed of rubber, shaped to yieldingly engage and slideV over the surface of the runways, and for fixed connection to the closure sections. On opposite sides of the boat and fixed to the gunwales thereof are longitudinalpacking strips 14, which slidingly engage the outer surfaces of the closure sections between the packing strips 13 thereon.` l f .v

To effect the adjustment and the watertight engagement between the longitudinal packing strips 14 and the closure sections, the latter are engaged at their inner opposite surfaces by the longitudinal tension bars or shoes 15, pivotally mounted upon the lonand in case of high seas may be looked to any desired degree, whereupon, in its action in opposition to the exterior packing strips 14, will secure the interposed closure sections 1ion ywater-tight relation with the body of the oat.

The platform 17 serves as seats or for general purposes of the passengers, cross seats 17a, on a corresponding level being provlded for the oarsmen, which latter seats are also preferably utilized as the kupper walls may be adjusted in any approved manner, v

steer the boat by means of the ropes 64, likef wise the sail may be controlled from this point by the several ropes and lines leading thereto.

As thus constructed, it will be obvious that the boat may be navigated by a single man and that full protection against adverse sea and weather conditions and imperfect ventilation will be afforded the passengers.

What I claim as my invention and desire to secure by Letters Patent, is:

l. A lifeboat comprising a hull, a deck extending above the gunwales of the boat and provided with an opening therein, a flexible closure for said opening having slidable Aconnections with the inner edges thereof, means for packing said slidfable connections, and joint means for operating said closure from above and below said decks.

2. A lifeboat comprising a hull, a deck extending above the gunwales of the boat and provided with an opening therein, a flexible two-section closure for said opening having slidable connections with the inner edges thereof, means for packing said slidable connections, and joint meansfor operati ing said closure sections from above and lbelow said decks.

3. A lifeboat comprising a hull having fore and aft deck sections bounding a midship opening, a pilot-pit extending through and opening above one of said deck sections and provided withia closed bottom, runways lprovided along the opposite inner edges of said deck sections, a flexible closure mounted in said runways and arranged to close said opening, and means leading exterior of said boat and adjacent said pilot-pit for operating said closure.

4. A lifeboat comprising a hull, a deck therefor extending above the gunwales of the boat and provided with an opening therein, a two-section closure for said opening having the meeting edges of said closure sections extending longitudinally of the boat, means for mounting said closure sections in sliding engagement with the inner edges of said opening, and means for jointly operating said closure sections to vary the freeboard of the boat.

5. A lifeboat comprising a hull, a deck therefor extending above the gunwalesA of the boat and provided with an opening therein, runways formed along the transverse opposite inner edges of said opening, a two-section flexible closure mounted in said runways and engaging the longitudinal edges of said opening and having the upper meeting edges of said closure sections eX- tending longitudinally of said boat, drums rotatable Withinl the boat and connected to the opposite lower longitudinal edges of said closure sections, and means acting through said drum for jointly operating said closure sections to vary the freeboard of the boat.

6. In a lifeboat the combination with the deck having an opening therein, of a exible closure for said opening having slidable connection with the inner edges of said opening, means for packing said slida.- ble connection, and means for operating said closure.

7. In a lifeboat the combination with the deck having Ian opening therein, of a lieXible two-section closure for said opening having slidable connections with kthe inner edges of said opening, means for packing said slidable connections, and means for operating said closure.

8. In a lifeboat the combination with the deck having an opening therein, of a flexible closure for said opening, a tubular air-chambered drum connected to said flexible closure, and means for rotating said drums.

9 In a lifeboat the combination with the deck having an opening therein, of a flexible two-section closure for said opening, tubular air-chambered drums connected to said closure sections, and means fori rotating said drums.

Signed at New York, in the county of New York and `State of New York, this 17th day of June, A. D. 1918.
